Complete Weiand 177 supercharger kit for Small Block Chevy. Features a 10-rib pulley system with two upper pulleys (3.48” and 2.85”), 6.5” lower pulley, and two belts. The lower pulley is 16-rib, but works perfectly with this setup.
On a mild 350 (≈350 HP NA), it makes ~5 lbs of boost with the larger pulley and ~9 lbs with the smaller pulley.
The kit is powder coated with a hammered finish, uses all chrome fasteners, and is in great overall condition.
⚠️ Will NOT work with Vortec heads.
